Narrative:

I was in the right seat providing instrument training to the pilot. We lost all electrical power en route to orc, continued to orc for landing. Did emergency gear extension, was unable to tell if gear was locked in the down position because of the electrical failure. I continued with normal approach and landing. Touched down on the main gear and the gear collapsed on rollout. Supplemental information from acn 476274: I was receiving instrument training in the left seat of the aforementioned aircraft. During the en route phase of flight to orc (VFR conditions at the time) we lost all electrical power. Continued to orc to land. The instructor performed emergency gear extension as per checklist. We were unable to determine the locked condition of the gear due to the power loss. The instructor continued with a normal approach and landing. After a successful main gear landing, the gear collapsed on rollout. We skidded on the runway with no damage to any airport property. Damage on the aircraft was limited to the propeller, step and scratching of the left inner flap area. There was no structural damage or personal injury involved.
